Alan in Antarctica

Where we are

  All directions are North from here.

  Antarctica is bigger than the United States.

  We are on Ross Island, approximately 80 km (50 miles) east-west and 80 km (50 miles) north-south.  The Dry Valleys are to the West and the Ross Ice Shelf touches the Island.

  Ross Island.  We are at the southern tip, at the end of Hut Point Peninsula, so-called, because Scott's Discovery Hut from his expedition to the South Pole is just here.  Mt. Erebus is the tallest mountain on the Island.

  Erebus Bay, to the west of Ross Island, showing the route we took on the Sea Ice School trip.

  Hut Point Peninsula.  We are at McMurdo Station.  Scott Base is the New Zealand research station, with 16 people now.  We landed at the place marked Ice Aerodrome.

 

The weather

NCAR runs a high resolution nested version of Polar MM5 every 12 hours, that I use for weather forecasts here.   It is called the Antarctic Mesoscale Prediction System (AMPS).

  Sunrise and sunset, Aug. 22, 2004.  The second line has a typo - it should be August 23.  While these are the official times of sunrise and sunset, the sky starts to get bright three hours before sunrise and we can see light inthe sky for three hours after sunset.  We cannot actually see the sun at McMurdo yet, as it is blocked by a mountain.  I understand that we will actually be able to see the sun here on Sept. 10.

  Today's weather discussion, Aug. 22, 2004.

  Weather forecast, Aug. 22, 2004.

  Windchill of -59C (-74F) on Aug. 23, 2004.  Luckily, we did not have to spend much time outdoors that day.

  Windchill of -66C (-87F) on Aug. 27, 2004.  I went on an hour town tour that day, and it did feel cold.

  The weather of Aug. 31, 2004, one of the colder days here.

  The weather of Sept. 4, 2004, an even colder day.

  We went to launch an ozonesonde this morning, Sept. 7, 2004, and just as we got the balloon inflated, a huge wind came in at 10 a.m., and we had to scrap the balloon and the launch.  I think it was just Mother Nature saluting me on my birthday.

  A rather low wind chill on Sept. 23, 2004.

 

Where we work - the Crary Lab, Cosray

  Our wing of the Crary Lab, center, next to the loading dock.  The Chalet is on the left.

  In my office.  I have my laptop set up in here.

  Linnea, Lou, and Jen in our lab, where we prepare the ozonesondes.

  While I held up the pipette for the picture, I actually was using it to add solutions to the ozonesonde as I conditioned it.  This is the first lab work I have ever done in my professional career.

  The setup where I condition the ozonesondes prior to launch.

  Cosray, on the road to Scott Base, Sept. 12, 2004.

  Cosray - the cosmic ray observatory where we receive transmissions from the ozonesonde to back up the main reception in the Crary Lab.

  Me monitoring the Aug. 25 flight at Cosray.

  The instruments at Cosray.  These are the latest technology, including a Toshiba T1000LE laptop.  Behind it on the right are the cassette tape recorder for backup and under that the modem.  On the left is the radio receiver, and behind it the two controls for moving the antenna up and down, and side to side.

 

Global warming lecture

  On September 5, 2004, I gave a Science Lecture in the Dining Hall to more than 100 people.  It was fun to give a talk on that topic in such a cold place.

  I ended with the Hummer graffiti slide.

  A number of people stayed around afterwards to ask more questions.

Volcano lecture

  I also gave a lecture on volcanic eruptions and climate on Oct. 3, 2004.
